The Planet Detection Test-bed is a lab based simulation of the optics and control systems for an interferometer based
Terrestrial Exoplanet characterization mission. The test-bed supports starlight nulling at 10um infrared wavelengths,
with fringe tracking at 2um wavelengths and angle and shear tracking at visible wavelengths. It further allows injection
of simulated planet light in the presence of the nulled star light, to allow testing of planet detection methods. We will
describe the detailed construction and operation of the test-bed from an optical and control system perspective. We will
also report the latest results for narrow band nulls, and the detection of broad band planet light in the presence of nulled
starlight.© (2008) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
